Abstract: The invention is directed to a process wherein a feedstock or stream comprising steam cracker tar is passed to a vacuum pipestill. A deasphalted cut of tar is obtained as an overhead (or sidestream) and a heavy tar asphaltenic product is obtained as bottoms. In preferred embodiments, at least a portion of the bottoms product is sent to a partial oxidation unit (POX) wherein syn gas may be obtained as a product, and/or at least a portion of the bottoms product is used to produce a light product stream in a coker unit, such as coker naphtha and/or or coker gas oil. In another preferred embodiment at least a portion of the overheads product is added to refinery fuel oil pools and in yet another preferred embodiment at least a portion of the overheads product is mixed with locally combusted materials to lower soot make. Two or more of the aforementioned preferred embodiments may be combined.

Abstract: A process is described for producing deasphalted steam cracker tar comprising feeding steam cracker tar to a vacuum pipestill (VPS) including a flash zone separated from a zone comprising trays by at least one annular entrainment ring and obtaining as an overheads a deasphalted tar product and as a bottoms an asphaltenic heavy tar product. Also according to the invention, there is a system for the upgrading of tar comprising said VPS with at least one annular entrainment ring.

Abstract: A capnograph system sensor head includes an airway adapter, a housing for receiving the airway adapter, a source of infrared radiation coupled to the housing for directing infrared radiation through the airway adapter, and a detector subsystem coupled to the housing and responsive to the infrared radiation after it passes through the airway adapter for providing an analog output. A circuit sub-assembly is integrated with the sensor head and includes a controller responsive to the analog output of the detector subsystem. The controller is configured to adjust the gain of the detector subsystem to output a digital signal representative of the amount of a particular gas flowing through the airway adapter.

Abstract: A method for correcting color of digital images generated by an image capture device is provided. The method includes evaluating a reference digital image of a real-life reference target on a viewing monitor, comparing at least one color in the reference digital image with a corresponding color in the real-life reference target itself, modifying the at least one color in the reference digital image by using a discriminative color correction process if the at least one color in the digital image deviates from the corresponding color in the real-life reference target, the discriminative color correction process producing at least one corrective color combination; and correcting the color of the digital images in accordance with the at least one corrective color combination.

Abstract: A gas stream monitoring system including a low cost main stream gas analyzer system is disclosed herein. The low cost main stream gas analyzer system is calibrated by a side stream gas analyzer system included in the gas stream monitoring system. Once calibrated, the side stream system is placed into standby mode such that diversions of portions of the gas stream can be minimized. The calibrated output signals from the low cost main stream system contain corrections for gas interference, pressure change, temperature change, manufacturing tolerance, component flaws, and any other sources of error.

Abstract: A moisture trap including a housing with an inlet and an outlet and defining a reservoir therein. A conduit in the housing extends through the reservoir from the inlet and the conduit has a distal open end spaced from the housing outlet. A hydrophilic filter canister is received in the housing filling the reservoir. The canister includes an end wall disposed over the distal open end of the conduit, the end wall having gas ports therethrough in fluid communication between the housing outlet and the distal open end of the conduit. A hydrophilic column extends from the end wall within the conduit for collecting liquid and wicking collected liquid into the reservoir. A hydrophobic filter is disposed between the hydrophilic filter canister and the housing outlet to block liquid from passing through the outlet.

Abstract: A liquid and gas separator system is disclosed, the liquid and gas separator system includes an inlet that receives a first gas sample. The first gas sample at least partially includes liquid introduced from a patient in a gaseous or liquid form. The liquid and gas separator system also includes a first chamber coupled to the inlet and configured to receive the first gas sample. The first chamber includes a drain aperture. An outlet is coupled to the first chamber and is configured to receive a second gas sample from the first chamber. The second gas sample is derived from the first gas sample, that is the second gas sample includes less liquid than the first gas sample. The second chamber is substantially sealed around the first chamber. The first chamber receives a combined gas and liquid from the inlet and separates at least some of the liquid from the gas. The first chamber is configured to have liquid deposited at the bottom of the first chamber.

Abstract: A method of stabilizing temperature effects on a gas analyzer includes transmitting infrared energy through a plurality of cells in a reference cell drum to a sensor in the gas analyzer. The plurality of cells include at least one cell containing a reference gas and at least one cell containing an air reference. The method also includes interposing a filter in at least one of the plurality of cells in the reference cell drum, wherein energy from the infrared beam is reduced. The method further includes rotating the reference cell drum such that the infrared energy fully passes through each of the plurality of cells for a limited period of time such that the sensor generates a substantial sine wave signal.

Abstract: An infrared gas analyzer and method employing one optical path which includes one infrared source, one sample cell containing the gas(es) to be analyzed, one infrared sensor and one infrared filter no matter how many gases are to be analyzed. The one optical path with one filter is utilized for both determining infrared source output and infrared absorption by the gas(es) to be measured.

Abstract: An underpad for use in absorbing waste products of an incontinent person reclining on a bed mattress comprises a liquid resistent backing having a central portion straddled by two opposite end seams. Liquid absorbent batting is mounted to the backing central portion. The underpad also has a pair of elastic straps of lengths sufficient to be fastened to opposite backing end seams and drawn tautly in generally mutually parallel relation with each other beneath the mattress with the backing placed atop the mattress. Fastening means are also included for fastening the ends of the straps to the backing opposite side portions.

Abstract: A moisture trap for use in a patient monitoring system, includes hydrophilic material contained within a housing for separating moisture from the patient's exhalations prior to those exhalations reaching the actual monitoring device. The housing is separated into a reservoir containing hydrophilic medium and a passageway through which the exhalations flow. The reservoir is isolated from the passage except for a restricted passage, that restricted passage providing the only exposure of reservoir hydrophilic material to moisture and gaseous medium flowing through the passageway. A hydrophilic body is also positioned in the passageway in the path of exhalation flow. A wick of hydrophilic material in the restricted opening connects the passageway and hydrophilic body in the passageway to the hydrophilic reservoir material. A hydrophobic member is positioned in the flow path of the exhalations to occlude and interrupt the flow path when the hydrophilic material becomes saturated and can no longer pick up moisture.

The composition, when applied to a thin metallic film, inhibits degradation of the thin metallic film as compared to the composition without calcium cyanamide. Processes comprising the step of applying a composition of the invention to a thin metallic film and articles comprising a thin metallic film and a layer of a hardened composition of the invention are also disclosed.

Abstract: A golf ball position marker holder has a pad joined with a flap with confrontable surfaces of the pad and flap formed of materials that interlock so as to releasibly grip one another. The flap has an aperture of a size and shape such that the spike of the ball marker may extend therethrough while its base may not.
